[0002] A hammer is a hand tool consisting of a hammerhead and a handle. It moves, deforms, or fixes an object by striking it. Common types include claw hammers and round-headed hammers. The hammerhead has a flat striking surface and a wedge-shaped nail-pulling surface. As an important part of the hardware industry, hammers, along with wrenches, pliers, and other tools, are used in construction, machinery, automobiles, and other fields. Hammers can be classified into more than 20 types according to their function, such as fitter's hammers, stonemason's hammers, and octagonal hammers. When using a hammer, the appropriate size should be selected according to the weight of the workpiece, and the connection of the hammer handle should be checked regularly. The hammerhead in a hammer crusher is a core component, and its material and shape must match the material characteristics to affect the crushing efficiency.
[0003] However, the current split-type hammer structure has the following problems: the traditional split-type hammer structure is inconvenient to replace the hammer head surface, the structure is often relatively simple, and it cannot improve the overall stability of the split-type hammer.
